Ear protection can be achieved with a 2$ ear protection. This is where your argument is invalid.
Actually, from an accident (harm) prevention stand point you are incorrect. The aim is to always to control the harmful condition as close to the source as you possibly can by engineering it out. PPE is a last resort. In this case making the firearm quieter is the most efficient way to prevent hearing damage.
Ya sure. You are right.
But its illegal.
Making a move on suppressors would be an instant political death for anyone elected. It will not change, especially with weak arguments like this.
It would be a whole other story if it was still legal and they were trying to make it illegal, that would worth a fight. Trying to make them roll-back that part of the legislation is hopeless.
Good luck. Keep dreaming
